Walton said she was in an outdoor dining area outside the Stadium’s Hard Rock Cafe when she put her foot on a metal hatch that had a power cord sticking out of it. The cord was being used to power some lights in a nearby tent. Walton, who describes herself as a multimedia artist, said she first started feeling electricity and then heard crackling like an electric transformer. Next thing she knew, stadium guards had rushed to her aid.

“I started getting a headache,” she said. “I couldn’t get myself together. I was shocked that I was shocked.”

The Flatbush woman said she was first taken to an aid station in the Stadium. She was then treated at the emergency room at Lincoln Hospital, according to hospital records.

Yesterday, she said, she was still suffering from headaches, memory loss, tingling and post- traumatic stress disorder.

Walton has hired attorneys Matthew Blit and Les Levine, who plan to file a $2 million suit against the Yankees and the Hard Rock.

“It was a jury-rigged system that was not safe for the public. They obviously didn’t care much about the risk — they care more about selling their expensive skyboxes,” Levine said.

Yesterday, a metal plate had apparently been put over the spot where Walton was shocked, Levine said.

Yankees spokeswoman Alice McGillion said, “A woman on the 4th alleged that she got a shock. We had EMTs check her out. We insisted that she go to the hospital, and as far as we know she was treated and released.”
